Detailed description of the invention
Presently in connection with drawings and Examples, the present invention is further detailed explanation, and these accompanying drawings are the schematic diagram of simplification, and the basic structure of the present invention is described the most in a schematic way, and therefore it only shows the composition relevant with the present invention.
As shown in Figures 1 to 5, a kind of backrest of automotive seat, including backrest frames, this skeleton has the shell 11 along its circumferentially extending form of an inverted " u " and the crossbeam 12 of connected with outer casing 11 both sides, the shoulder of shell 11 is rotatably connected to safety belt guide plate 20, and limit safety belt guide plate 20 support spring 30 of rotational angle on shell 11 shoulder, specifically can weld one piece in safety belt guide plate 20 side towards the square gripper shoe 40 bottom shell 11, the two ends of support spring 30 are connected on the both sides of shell 11, the supporting part 31 of support spring 30 is resisted against in gripper shoe 40.Concrete, support spring 30 in the present invention has the anchor portion 32 of bending, and connect the supporting part 31 of two anchor portion 32, this supporting part 31 has some straightways 33 being sequentially connected with, connect the supporting section 34 in " " shape of straightway 33, the straightway 33 at supporting part 31 two ends is connected with two anchor portion 32 the most in obtuse angle.The present invention is by being arranged on safety belt guide plate 20 on the side of the shoulder of skeleton, when using of seat belts, no matter backrest is adjusted to where and which kind of angle, safety belt guide plate 20 together adjusts with backrest all the time on the shoulder of skeleton, it is ensured that both remain at optimal, on safest position relationship.Because safety belt is to pull out to pass from safety belt guide plate 20 from coiler, therefore, safety belt can produce friction with safety belt guide plate 20, the most glibly safety belt can not be pulled out, therefore, safety belt guide plate 20 is rotatably connected on by the present invention on the shoulder of shell 11, when pulling out safety belt on safety belt guide plate 20, safety belt guide plate 20 can rotate along the direction of safety belt pull-out and adjust its angle on housing shoulder, with the friction of less generation；For avoiding safety belt guide plate 20 arbitrarily to rotate on the shoulder of shell 11, its rotational angle on shell 11 shoulder can be limited by support spring 30, elastic stress is there is between supporting part 31 and the anchor portion 32 of the support spring 30 in the present invention, make supporting part 31 can press to anchor portion 32, also can turn up towards the outside of anchor portion 32, and under the effect of this elastic stress, recover nature, therefore, the supporting part 31 of support spring 30 is connected in gripper shoe 40, when safety belt guide plate 20 is when rotating, utilize the elastic stress of support spring 30 self, the safety belt guide plate 20 after rotation is made to revert to its optimum position on shell 11 shoulder.
Preferably, the present invention is horizontally connected with several rows tensioning apparatus between shell 11 both sides from top to bottom, the extension spring 52 of the wave-like that this tensioning apparatus includes being arranged on the tension spring hook 51 on inside shell 11 both sides and two ends are hooked in tension spring hook 51 respectively, concrete, for preferably the support force from waist to shoulder can be provided to occupant, this tensioning apparatus of three row can be horizontally connected with between shell 11 both sides from top to bottom.Occupant is when riding in an automobile seat, the back of occupant is to be pressed on the backrest of seat, the extension spring 52 of wave-like can occur corresponding deformation according to the pressure that backrest is applied by occupant, thus corresponding support force is provided, and the extension spring 52 of wave-like is relatively big with the area of occupant's back contact, occupant will not be made to feel uncomfortable.
Further, the backrest of the present invention also includes the backrest base 61 being arranged on shell 11 both ends, and shell 11 two ends are pivotally attached on base 61 by connection angle regulating part 62 respectively, the rotating shaft 63 running through two angle adjusting pieces 62 it is horizontally connected with between two bases 61, wherein an angle adjusting piece 62 is provided with the fixing seat 65 of fixing motor 64, motor 64 order about rotating shaft 63 and drive two angle adjusting pieces 62 to overturn along two bases 61 respectively.Motor 64 drives the drive mechanism of backrest upset adjusting angle of backrest to be means commonly used in the art, the most no longer describes in detail.Concrete, between two angle adjusting pieces 62, it is also associated with being pressed on it respectively the U-board 80 on shell 11 two ends, the two side of U-board 80 wraps up the outside of two angle adjusting pieces 62 respectively, prevents two angle adjusting pieces 62 from producing relative displacement when driving backrest frames to rotate with shell 11.
Further, the shoulder of shell 11 is additionally provided with the sleeve pipe 70 installing headrest guide sleeve, specifically can offer the locating slot 13 mated with sleeve pipe 70 on the shoulder of shell 11, the outer wall of sleeve pipe 70 is welded in locating slot 13, easily fabricates.
Desirable embodiment according to the present invention is enlightenment above, and by above-mentioned description, related personnel can carry out various change and amendment completely in the range of without departing from this invention technological thought.The content that the technical scope of this invention is not limited on specification, it is necessary to determine technical scope according to right.
